$600 Billion Vanishes from AI Chip Giants in One Day

More than $600 billion in market capitalization evaporated from the leading “pickaxe sellers” in the artificial intelligence industry during a single trading session yesterday, as a wave of selling spread from Nvidia to Broadcom, TSMC, Samsung, and SK Hynix, signaling that investors are reassessing the key bet that has driven global equity markets over the past two years.

This AI stock sell-off did not begin this week with developers of large language models or chatbot applications, but rather with companies in the industry’s value chain essential to building the technological revolution itself.

In one of the sharpest selling episodes the sector has seen this year, shares of major chip manufacturers and AI infrastructure suppliers came under intense pressure, wiping out more than $600 billion in market capitalization from the eight largest companies linked to the hardware powering AI models.

Shares of Nvidia, TSMC, Samsung, SK Hynix, Broadcom, and AMD fell after calls from AI company leaders to slow the development of the most advanced models sparked investor concerns about a potential slowdown in the massive spending that has supported the sector for over two years.

The real winners in major booms are not always the gold seekers, but the companies that sell them the tools needed to search for gold.

Nvidia sells the processors that power AI models, while TSMC manufactures most of those chips. Samsung and SK Hynix produce the advanced memory chips required to train large models, while Broadcom provides the networking infrastructure that connects thousands of processors within data centers, and AMD is striving to capture an increasing share of the AI accelerator market dominated by Nvidia.

Nvidia was the biggest loser in terms of market capitalization, with its share price falling by approximately 3.9%, erasing about $200 billion from its market value in a single session.

TSMC also lost around $75 billion in market capitalization, while SK Hynix suffered losses nearing $61 billion after a decline exceeding 6%, and Samsung Electronics lost nearly $49 billion.

The selling wave extended to AMD, which lost about $46 billion in market capitalization, as well as Broadcom, whose value dropped by approximately $65 billion.

Adding up these losses, the market capitalization wiped out surpassed the half-trillion-dollar threshold in a single session, a figure that reflects the scale of bets investors have placed on the continuation of the AI boom at its current pace.

However, Monday’s session showed that investors have become more sensitive to any signal suggesting that the pace of spending on data centers and advanced chips may not continue indefinitely.

While major technology companies continue to pour hundreds of billions into AI infrastructure, the collapse of the “pickaxe sellers’” shares indicates that the market has begun to test the premise underlying the largest rally the technology sector has seen since the advent of the internet.
